The utility model provides a thread rolling machine for a reverse gear intermediate shaft, which has high safety coefficient and is used for making up the defects of the prior art.

The utility model is realized by the following technical scheme:

the utility model provides a reverse gear jackshaft is with thread rolling machine, includes the frame, be equipped with two thread rolling rollers in the frame, be equipped with the blade disc between two thread rolling rollers, characterized by, be equipped with the riser in the frame, the riser is located the extension line of blade disc, it has the rectangular shape hole of upper and lower direction to open on the riser, a supporting screw rod in rectangular shape hole, the supporting nut of screw rod, the screw rod is towards the one end fixed connection fixed plate of blade disc, be equipped with two gyro wheels of arranging about on the fixed plate, middle part between two gyro wheels is just to the blade disc.

The upper end of the vertical plate is an arc-shaped groove capable of accommodating the top end of the reverse gear intermediate shaft.

The articulated arc of arc wall one end, an articulated screw pole of free end of arc, the supporting screw cap of screw pole, the arc wall other end has set firmly the flat board, it has the breach that can hold the screw pole and pass through to open on the flat board.

The utility model has the beneficial effects that:

the reverse gear intermediate shaft is limited in position through the idler wheel and the arc-shaped groove in the vertical plate, manual limitation in operation is replaced through the matching of the idler wheel and the arc-shaped groove in the vertical plate, the possibility of personnel damage is avoided, and the reverse gear intermediate shaft is simple in structure, convenient to operate, high in safety coefficient and high in efficiency.

Drawings

The utility model is further described below with reference to the accompanying drawings:

FIG. 1 is a schematic front view of the present invention;

FIG. 2 is an enlarged schematic view of the structure at A in FIG. 1;

FIG. 3 is an enlarged schematic view of the structure at B in FIG. 2;

FIG. 4 is a top view of a portion of the present invention (with the curved plate open);

fig. 5 is a right-side view of the fixing plate in fig. 1.

In the figure, 1 frame, 2 thread rolling rollers, 3 cutterheads, 4 vertical plates, 41 long-strip-shaped holes, 42 arc-shaped grooves, 5 screw rods, 6 nuts, 7 fixing plates, 8 idler wheels, 9 arc-shaped plates, 10 screw rods, 11 screw caps, 12 flat plates and 121 gaps.

Detailed Description

The drawings illustrate specific embodiments of the utility model. As shown in fig. 1 to 5, the thread rolling machine for the reverse gear intermediate shaft comprises a frame 1, two thread rolling rollers 2 are arranged on the frame 1 in a left-right manner, the two thread rolling rollers can move left and right, a cutter head 3 is arranged at the middle position between the two thread rolling rollers 2, a vertical plate 4 is further arranged on the frame 1, the plane of the vertical plate 4 is in the left-right direction and is positioned on the extension line of the cutter head 3, a long-strip-shaped hole 41 is formed in the vertical plate 4, a screw rod 5 is matched in the long-strip-shaped hole 41 in the up-down direction, the screw rod 5 penetrates through the long-strip-shaped hole 41 and can move up and down in the long-strip-shaped hole 41, the outer end of the screw rod 5, namely one end far away from the cutter head 3, is connected with a nut 6 in a threaded manner, a fixing plate 7 is fixed at the inner end of the screw rod 5, namely one end facing the cutter head 3, and the fixing plate 7 can be fastened at any position within the range of the long-strip-shaped hole 41 through the matching of the screw rod 5 and the nut 6, that is, the position of the fixing plate 7 can be adjusted by the screw 5 and the nut 6. Two rollers 8 are arranged on the fixed plate 7 in the left-right direction, and the middle position between the two rollers 8 is positioned on the extension line of the cutter head 3; the top of riser 4 is arc wall 42, the top of the T font of reverse gear jackshaft can be put down to this arc wall 42, an articulated arc 9 of one end of arc wall 42, an articulated lead screw 10 of free end of arc 9, a supporting screw cap 11 of lead screw 10, dull and stereotyped 12 of other end fixed mounting of arc wall 42, a breach 121 is opened on dull and stereotyped 12, after the arc 9 changes, lead screw 10 card goes into in breach 121, and arc 9 forms a closed loop with arc wall 42, this closed loop is a little more than the top of the T font of reverse gear jackshaft, do not hinder the rotation of reverse gear jackshaft. The notches 121 may be opened at the end and both sides of the flat plate 12 according to the positions of the lead screw 10 and the lead screw 11. The rollers 8 may be replaced by bearings.

The using process is as follows:

start the thread rolling machine, put the jackshaft that reverses gear on blade disc 3, reverse gear in the arc 42 is put on the top of the T font of jackshaft, then roll over arc 9, form the closed loop with arc 42, screw rod 10 inserts in breach 121, need not fastening screw cap 11, screw cap 11's effect only prevents to lead to the arc 9 to rebound the normal position at the vibrations of the jackshaft that reverses gear at the thread rolling in-process, loses the constraint effect to the jackshaft that reverses gear already. The reverse countershaft can still rotate freely at this time.

After the thread rolling of one reverse gear intermediate shaft is finished, the arc-shaped plate 9 is opened, and then the other reverse gear intermediate shaft is replaced.

Other technical features than those described in the specification are known to those skilled in the art.
